Q. The volume of a rectangular prism is 360cm3. Alex measures the sides to be 9.09cm by 4.84cm by 8.35cm. In calculating the volume, what is the relative error, to the nearest hundredth.Answer:
Given: Given: The actual volume of the rectangular prism Vactual = 360cm3Measured dimensions: length l = 9.09cm, width w = 4.84cm, height h = 8.35cmCalculate the measured volume Vmeasured using the measured dimensions.Vmeasured=l×w×h360cm30
Calculate Volume: Perform the multiplication to find the measured volume.Vmeasured=9.09cm×4.84cm×8.35cmVmeasured=367.03914cm3
Perform Multiplication: Calculate the absolute error, which is the difference between the measured volume and the actual volume.Absolute error = ∣Vmeasured−Vactual∣Absolute error = ∣367.03914cm3−360cm3∣Absolute error = 7.03914cm3
Calculate Absolute Error: Calculate the relative error by dividing the absolute error by the actual volume and then multiplying by 100 to get the percentage.Relative error=VactualAbsolute error×100Relative error=360cm37.03914cm3×100
Calculate Relative Error: Perform the division and multiplication to find the relative error.Relative error = (7.03914cm3/360cm3)×100Relative error = 0.01955317×100Relative error = 1.955317%
Round Relative Error: Round the relative error to the nearest hundredth.Relative error ≈1.96%
